In this user's manual, the following precautions and signal words are used to provide information to ensure the safe use of the MX2 Inverter.The information provided here is vital to safety. Strictly observe the precautions provided.

• Meanings of signal words

• Alert symbols in this document

Indicates an imminently hazardous situation which, if not avoided, is likely to result in serious injury or may result in death. Additionally there may be severe property damage.

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage.

Turn off the power supply and implement wiring correctly. Not doing so may result in a serious injury due to an electric shock.

Wiring work must be carried out only by qualified personnel. Not doing so may result in a serious injury due to an electric shock.

Do not change wiring and slide switches (SW1), put on or take off Digital Operator and optional devices, replace cooling fans while the input power is being supplied. Doing so may result in a serious injury due to an electric shock.

Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or fire.(200-V class: type-D grounding, 400-V class: type-C grounding)

Do not remove the terminal block cover during the power supply and 10 minutes after the power shutoff.Doing so may result in a serious injury due to an electric shock.

Do not operate the Digital Operator or switches with wet hands. Doing so may result in a serious injury due to an electric shock.

Inspection of the Inverter must be conducted after the power supply has been turned off. Not doing so may result in a serious injury due to an electric shock.The main power supply is not necessarily shut off even if the emergency shutoff function is activated.

DANGER

CAUTION

DANGER


Do not connect resistors to the terminals (PD/+1, P/+, N/-) directly. Doing so might result in a small-scale fire, heat generation or damage to the unit.

Install a stop motion device to ensure safety. Not doing so might result in a minor injury. (A holding brake is not a stop motion device designed to ensure safety.)

Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result in a moderate burn due to the heat generated in the braking resistor/regenerative braking unit. Configure a sequence that enables the Inverter power to turn off when unusual overheating is detected in the braking resistor/regenerative braking unit.

The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or other property. Place covers on the openings or take other precautions to make sure that no metal objects such as cutting bits or lead wire scraps go inside when installing and wiring.

Do not touch the Inverter fins, braking resistors and the motor, which become too hot during the power supply and for some time after the power shutoff. Doing so may result in a burn.

Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the Inverter capacity on the power supply side. Not doing so might result in damage to property due to the short circuit of the load.

Do not dismantle, repair or modify this product.Doing so may result in an injury.

1 OVERVIEW

1.1 Introduction

This user’s manual explains how to use the Pump Sequencer Application program for 3G3MX2 inverter. Be sure to read this user’s manual carefully before using this Pump Sequencer Application program, and keep it on hand for further reference.

Traditionally, pump systems when reaching certain capacity require splitting the pump unit of big capacity into smaller one. Then it is a simple way to keep pressure in the circuit within certain limits in steps, just starting and stopping this pumps, thus saving energy as the flow demand variation is big and not all the pumps are required all the time... With the introduction of Variable Speed Drives the technology allowed contin-uous and smooth control through closed loop pressure sensor PID control loop. This provide the best circuit response and implemented means of reducing the stress in the piping system when pumps were directly started.

1.2 Handling of this user’s manual

The contents of this user’s manual are subject to change without prior notice. No part of this user’s manual may be reproduced in any form without the publisher’s permission.

If you find any incorrect description, missing description or have questions concerning the contents of this user’s manual, please contact the publisher.

1.3 Safety instruction

Be sure to read this user’s manual, inverter user’s manual, and appended documents thoroughly before using Pump Sequencer Application pro-gram and the inverter. Ensure you to understand and follow all safety information, precautions, and operating and handling instructions for the correct use of the inverter. Always use the inverter strictly within the range of specifications described in the inverter user’s manual and correctly implement maintenance and inspection to prevent fault from occurring. When using the inverter together with optional products, also read the manual of those products. Note that this user’s manual and the manual for each optional product to be used should be delivered to the end user of the inverter. In this user’s manual you can find WARNING along the instruction WARNINGS: indicates that incorrect han-dling may cause hazardous situation, which may result in serious personal injury or death.

Note: 3G3AX-EIO21-ROE (extra input/output option board) cannot be used with this Drive Programming case software.

1.4 Current problem / solution

When it comes to big capacity pumping, using a unique big pump and inverter for smooth control becomes too expensive solution... Then a hybrid solution of a modulated pump and several auxiliary fixed speed pumps with intelligent sequencing controller was found to be an opti-mal solution...

1.5 Features of the application software

Pump sequencer software provides within the inverter logic functionalities to control a system of pumps where one pump is being controlled in speed and others are started and stopped by system pressure demand and conditions... The pressure in the system is closed-loop controlled and advanced PID controller also integrated in the inverter. The herewith presented case software implements both PID regulation and multi-ple configurable slave pumps handling, to provide a compact and flexible solution for pump control systems.

The software described in this document allows the control of a system of up to 3 auxiliary pumps. We have following pump functionality:

All in one: Inverter houses all control.

Physical units: Set Point and Present value readout in %.

Modulated pump control:• Starting and stopping configurable conditions from feedback pressure reading, output frequency and auxiliary pump status.• Minimum and maximum speed for controlled pump modeling.

• Advanced PID control.



Auxiliary pumps control:• Definable amount and control of auxiliary pumps up to 3 with MX2 inverter.• Starting and Stop conditions based on modulated pump output.

Pressure/flow/level feedback signal: 0-10 V sensor, 0-20 mA, 4-20 mA.

Modulated pump automatic frequency drop/rise (water hammer effect cancellation): At startup/stop of auxiliary pump with configurable conditions. This compensates the peak of pressure appearing when a fixed speed pump is activated.

Automatic auxiliary pumps: The auxiliary pumps with less running time will be started first. Duty cycle for each pump can be 100% or 50%, which means a pump with 50% duty will work half the time of others.

Specific faults and alarms:• Break: Feedback sensor breakdown fault.• Feedback limit alarms (Hi, Lo faults).

Pump working time totalizers: Individual for each pump and inverter.

Test operation: In this mode it is possible to manually control the start/stop of auxiliary fix pumps for test purposes.

2 PREPARATION AND SYSTEM CONFIGURATIONTo prepare the inverter for operation, the configuration tool CX-Drive is used for setting parameters and to download the Pump Sequencer Application program. In the following chapters we will show the necessary steps to set up the inverter for a pump sequencer application. We will use 3G3MX2 inverter.

2.1 Installation and power circuitsThis manual does not cover how to install the inverters in cabinets, how to wire power supply or how to satisfy other application specific requirements. Please, refer to the MX2 User’s Manual (I570-E2).

PUMP SEQUENCER APPLICATION FUNCTIONS

4.5 Sleep function

Modulated pump internal run command will shut off, if the output frequency monitor (d001) becomes less than the sleep frequency level (P114), during a specified period (P116).After that, if the PID deviation monitor (d153) exceeds the PID deviation level value (P115), during a specified period (P117), the internal run command will be restarted.

Caution: Drive Programming PID sleep function is always enabled if the frequency level is different to 0 (P114 <> 0), PID enable parame-ter is set to 1: Enabling, parameter A156 and A157 are set to 0.0 and Drive Programming program is running (A017 = 2: Always ON). If Drive Programming program is running and parameters A156 (PID sleep function action threshold) and A157 (PID sleep function action delay time) have different values to 0, there will be a DP PID sleep malfunction, so the internal inverter PID sleep function will be running, too.


P114 Sleep frequency level 0 to max. freq (A004) - 2100[21.00 Hz]

Sleep level default to 21 Hz (recommended set-ting is a bit higher than the minimum speed of the pump in P108)

4.6 Disconnection detection

It detects a feedback disconnection when the PID feedback is under the programmed PID disconnection level.

Note: At first start-up, even if the PID-FB is under the programmed level, no trip will be performed, but, after this first start-up, if PID-FB over-pass the programmed level, PID disconnection function will perform a trip if the PID-FB goes under the PID disconnection level (P123).
